This invention relates to trucks,more parmy invention embodies a top frame compre- I ticularly tohan'd trucks such as ordinarily used inhandling freight in loading-and unloading railroad cars and ships, aswell as in I} transporting heavy or bulky packages in manufactories, Warehouses, etc. I,

More specifically, my invention is concerned with handtrucks having bodies made from'sheet metal; and in such connection I 1 aim to secure the utmost strength and rigidity with employment of a-minimumamount of-material. This end is attained as hereinafter fully set forth, through provision of an 'open frame withside bars and intermediatelongitudinals connected at intervals by'ja nuinber of transverse or cross bars.

My: invention is. also inypart directed toward provision of supplemental means for reinforcing the truck frame where additional strength is desirable, or Where distortion is solid obstructions under rough usage.

' I generahI aim to'se curethe advantages 7 of "structural lightness and manu'facturing 5 economies resultant upon. employment [of in* thecohStruction of hand sheet metal trucks. 7 a

Still other objects and attendant admit tages of this invention will appear fromthe. detailed: description which follows 'ofthe typioallembodiment' shown in theattached of my improved hand-truck.

hensively designated by the numeral 10, the same being in the form of a die stamping struck from a single piece of sheet metal with slightly divergent side rails or bars '11, 11

and an intermediate longitudinal 12, which sidebars and longitudinal are joined at intervals by a series of transverse or cross bars 13, 14, 15. From Fig. IV it will be observed that the side bars 11 are of hollow'channel cross section open at the bottom, and moreover that they rise well above the plane of the transversebars 13'15, therebybetter adapting the truck for support and retention of convex surfaced packages like barrelsfor example. Along theirl loweredges the lateral facesof the side bars 11 are outwardlyfjoggled as at 17, 18 with formation of longitudinal 12 has a cross sectional configuration exactly like that ofithe transverse bars 13 ,16, but its medial embossment 21 terminates short of the embossments 20 of said transverse bars with avoidance of intersections as is manifest from Fig. I.

Into the hollows of the side bars of the frame atone end of the truck are fitted the squared shanks of handles 22 which are preferably constructed from wood and bowed or rounded for convenience and comfort in gripping them;

v As ameans to reinforce the upper cross bar 13 of the frame,'I provide a supplemental bar 25' having a counterpart channel cross section dimensioned to 'fit within the hollow of said transverse bar, as seen in Fig. VI. The supplemental bar 25 is stiffened by anupward medi'al'embossment 26which is adapted to contact with the embossment of the transverse bar v13jwhenthe parts are assembled as I I v p p I shown in Eigl VI. v The ends of the supple- As hereindelineated, the hand truck fof mental bar are flattened as at 27*, 27' to bridge the openfbettom bi the sidebars 11* while contacting with the lower faces ofthe i shanks of the handles22. As shownin Figs;
